Reliability and Validity of the Modified Prone Press Up Test as an Evaluation Index of Thoracolumbar Extension Mobility

Abstract

[Purpose] This study investigated the reliability and validity of the Modified Prone Press Up Test (MPPUT), which was devised to easily assess thoracic spine extension mobility. [Participants and Methods] The MPPUT, Ott’s Test (OTT), and Modified-Modified Schober Test (MMST) values of healthy adults from two different facilities were measured. [Results] MPPUT showed high intra- and inter-rater reliability. Furthermore, a positive correlation was found between MPPUT and OTT, but no significant correlation was found between MPPUT and MMST. [Conclusion] The results suggest thoracic spine extension mobility can be evaluated using MPPUT.
